National Signal

We are a U.S. company with worldwide sales specializing in electronic Directional DisplayÔ panels, variable message signs, speed control products, and other equipment for the traffic control industry. Our products represent the most current technology designed for ease of use and maximum abuse. Our Directional DisplaysÔ utilize advance controls without moving switches. The "touch sensitive" panel eliminates mechanical switches which get wet or break causing costly down time on equipment. Our controls even monitor the vehicles battery voltage and turns the panel off to avoid a dead battery. Our Directional DisplaysÔ utilize proprietary, low wattage, polycarbonate lamps as well as very high brightness LED (light emitting diode) lamps. We manufacture a complete line of message signs and speed control products giving our customers a wide selection of products for virtually every application. With our UniCPU available in our message signs and speed displays, programming is simple because the computers are the same. Our message signs and speed displays use common components. Turn your message sign into a speed sign or your speed sign into a message sign. Aside from our own standard equipment, we also build special equipment to suit. We design and test all our own products in our Santa Fe Springs facility. We also manufacture almost 100% of our equipment. We can design special controls, solar recharging systems, and special electronic message signs of various sizes.
